Where: Queensland, Australia (22.4° S, 147.9° E: paleocoordinates 57.6° S, 140.3° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Back Creek Group, Wuchiapingian (259.9 - 254.2 Ma)

• Clarkei bed likely belongs to the Pseudostrophalosia clarkei zone, correlated with the lower part of APP4.3 palynomorph zone (Briggs, 1998). The APP4.3 zone was constrained as mid-Wuchiapingian age by U-Pb dating in Laurie et al. (2016).

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified siliciclastic sediments

Size class: macrofossils
